Getting FLTK to run without issues in the browser

[Mo_Al_]

Hi all,

I'm working on getting FLTK to work on the browser. Support code here:

https://github.com/MoAlyousef/fltk_wasm32_emscripten/tree/emscripten
(under the emscripten branch)

Demo here:

https://moalyousef.github.io/fltk_emscripten/

I use emscripten_sleep() in the event loop. This is needed for shown dialogs and menu windows. However due to it not supporting reentrancy, I sometimes get crashes/errors when spawning a dialog or menu window.

I'm wondering if you have suggestions to work around that?
Is there a way to detect that emscripten_sleep() is currently waiting and avoiding reentrancy?

I appreciate all suggestions.
Thank you

How is this used I have looked at the gif repository, and it looks exactly like the default fltk library.  Does this compile with an emcc *.cpp -o demo.html command?

I managed to get FLTK to compile with the emcmake commands, but how do I target external code in other folders?

I’m not sure I understand the question. 

Do you mean build your code which uses FLTK?
